To all whom, it may concern:

Be it lmown that I, EMMA S. COLEMAN, a citizen of the United States. residing at Beatrice, in the county of Gage and State of Nebraska, have inventeda new anduseful Composition of Matter to be Used for Rendering Paper Impervious to Air and Moisture, as set forth in the ensuing specification.

My composition consists of the following ingredients combined in the proportions stated, viz.

Pure grain alcohol lpart. Pure olive oil lpart. Sheet gutta-percha dissolved in chloroform 9 0i 1st part.

Sheet gutta-percha is named in preference to the gutta-percha chips as it dissolvesodor, chloroform is named. The olive oil Specification of Letters Yatent.

and dissolved gutta-percha, must first be thoroughly mixed by. stirring; the alcoholmay then be added and all mingled by agi- Patented Nov. 2, 1915.

tation. The composition obtained may then be applied to each side of the paper, and the paper dried. The oil and gutta-percha fill the pores of the paper. 1 The alcohol aids the other two ingredients to dry in addition to diluting them to a proper consistency. When dry the-paper will resist moisture and, if gathered closely togetherat the edges the air may be excluded. The pliability and fiber of paper treated by the composition described herein will be found to remain intact.

I claim: The herein-described composition of matter consisting of alcohol, olive oil anda solution of gutta-percha, in the proportions stated, and for the purpose of rendering paper impervious to air and moisture.
